Can I mount a DC-DC converter and have some kind of switch to turn it on so it runs on 24v when switch is on and 12v when its off, is that possible to make? How do i wire it in that case?

2x7,2aH SLA batteries, DC-DC converter to 24v will that make it play for 8h?

The Sure ST508 is tried and tested here. Wel-behaved, reliable at  24V, 4R loads
REMEMBER....POLITICIANS AND DIAPERS SHOULD BE CHANGED OFTEN AND FOR THE SAME REASON

Jag tänker att det är ingen differens är det metalfilm eller inte. Men jag är inte 100% säkert om det. Om jag försår din fråga rätt LOL Kul att skriva på svenska lite om jag är inte mästaren av det Big smile
